Did the turbo dump a bunch of oil into the CAC and you are getting residual oil burning out? Just some random thoughts for you.

Smoke is blue grey to black on hard pulls. But consistently blue grey. No crankcase pressure. Old turbo didn’t spit any oil. VGT just came apart bearings and seals still all good. No smoke on idle
